President Trump ended his second Situation Room final determination on Friday 29 May without a signature, then posted three public conditions Iran rejected within hours.

Key takeaway

the MOU stays unsigned; public demands from both sides have narrowed the diplomatic corridor.

President Donald Trump convened a second White House Situation Room meeting on Friday 29 May, billed as his final determination on the tentative 60-day Memorandum of Understanding (MoU). After two hours he signed nothing, then posted that Iran must "never have a Nuclear Weapon or Bomb", that the Strait of Hormuz open "immediately, no tolls", and that Iranian mines clear within 30 days⁠1.

Iran's foreign ministry replied that there were "no negotiations" on its nuclear programme, and Fars News, an IRGC-linked Iranian agency, called the conditions a contradiction of the draft 60-day framework the two sides have circled for weeks.

Trump claimed in his Friday post that the deal was largely settled, while CENTCOM that same weekend put a Hellfire missile through a cargo ship's engine and a suspected mine drifted into Omani waters. His forces moved from waving ships off course to disabling one by munition. The posted demands are words; the missile and the mine are what his forces and the strait actually did.

Iran's rejection tracks the Supreme National Security Council line of 29 May, which framed the unsigned MoU as a 10-point Iranian victory with enrichment recognised. Neither side can move publicly without appearing to concede first.

Deep Analysis

In plain English

Trump held a second high-level meeting to decide whether to sign a deal that would reopen the strait of Hormuz, a narrow waterway through which roughly one-fifth of the world's oil flows. He walked out without signing, then posted three demands on social media: Iran must give up nuclear weapons permanently, open the strait immediately with no fees, and clear its mines within 30 days. Iran's foreign ministry spokesperson rejected the nuclear demand within hours, stating the programme is off the table. Both sides have now stated, publicly, positions they cannot back down from without losing face at home. That public gap is why markets are nervous: a deal that everyone hoped was close now looks further away.

Deep Analysis
Root Causes

Iran's SNSC requires any text to recognise the right to enrich uranium on Iranian soil, because domestic legitimacy since 2015 has been built on that premise. Trump requires visible nuclear forswearing, because his domestic base framed the war as a disarmament campaign from day one. Those two requirements are structurally incompatible on a single page.

Neither side can move without a domestic narrative shift. Iran cannot trade away enrichment recognition without SNSC internal fracture. Trump cannot accept a text that omits nuclear forswearing without his base reading it as Obama-era capitulation.

What could happen next?
  • Risk

    A deal-collapse reprice from $92 Brent has no floor: the entire $20 monthly fall was deal-optimism premium, not fundamentals-driven.

  • Consequence

    The House War Powers vote rescheduled to 2 June arrives after the operative period it was meant to govern, leaving the executive unconstrained for a third consecutive deadline.

    Immediate · Assessed
  • Risk

    Pakistan's role as sole remaining diplomatic channel becomes structurally fragile if Trump publicly expands his three conditions, as Islamabad cannot relay terms Khamenei has publicly pre-rejected.

Different Perspectives
United States (Joint Maritime Information Center)
United States (Joint Maritime Information Center)
The JMIC, the US-led naval reporting cell, rated the Hormuz threat "severe" in its 25 October advisory, as reported by gCaptain, and warned of possible renewed mining. Eight days earlier it found no substantiation for the Guards' mine claims, while US-facilitated transits ran at about 34 a day.
United Kingdom (CPS and Counter Terrorism Policing)

The CPS charged two men under the National Security Act 2023 over the RAF Fairford incident, and Counter Terrorism Policing said it believes the foreign intelligence service involved is Iran's, LBC reported. The case now runs through the courts; both men are charged, not convicted.

The Houthis told people to leave Aden airport, in the government-held south, before a missile fell there on 28 October, AFP reported, and police reported a second attack that afternoon. The fight between Riyadh and the Houthis is landing on the south's main civilian airport.
Qatar (mediators)
Qatar (mediators)
Qatar-led mediators put new terms to Iran this week, which an Iranian official called "ideas, not a proposal". Riyadh framed the Tehran meeting as support for Qatari and Pakistani mediation, keeping Doha at the centre of the indirect channel.
Korea Shipowners' Association
Korea Shipowners' Association
The association said the ships Iran listed were sub-chartered to an overseas oil company, not owned by Sinokor, carried no South Korean crew, and that Sinokor was unaware of the warning. South Korea's shipowners are contesting whose vessels the notice covers before it takes effect.
Kuwait (foreign ministry)
Kuwait (foreign ministry)
Kuwait summoned Iran's ambassador, Mohammad Toutounji, and handed him a protest note over the embassy's denial that its citizen took part in the alleged plot against Interior Minister Fahad Al-Yousef. Kuwait is answering through its courts and a diplomatic protest, citing international law and the UN Charter.
